Specification of Letters Patent.

Patented Dec. 31, 19.12.

Application filed December 15,1911. Serial No. 665,978.

To whom t'tmay concern:

Be it known that 1, PAUL E. Bt'rrow, a

' citizen of the United States, and a resident of the city of New York, borough 01' Brooklyn, in' the county of Kings and State of New York, have invented a new and 1111- proved Life-Boat, of which the following is a full, clear, and exact description.

My invention relates to a life boat, and an object of my invention is to provide an open top power boat, which cannot fill by the breaking of the seas over the same, and which is so constructed as to obtain the maximum bearing surface upon the water, and which has its center of gravity relatively low.

A further object of my invention is to provide a boat structure in which the maximum etliciency is obtained from the propellers by disposing the same within the outlines of the boat.

I attain the above-outlined objects by bellying the boat on opposite sides of the keel, to spread the same transversely over a material surface of the water, and providing a centrally-disposed opening in the bottom and stern of the boat.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of referenee indicate corresponding parts in all the figures, and in which Figure 1 is a side elevation of the skeleton of my improved boat; Fig. :2 is a trans-- verse sectional view taken on the line 22 and looking in the direction of the arrow; Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 1, looking in the direction of the arrow; Fig. i is a plan view looking down upon my boat, certain por tions of the boat being broken away, to

. show the construction of the smile; Fig. 5

is a horizontal sectional view taken on the broken line 55 and looking downward in the direction indicated by the arrow, and Fig. 6 is a view similar to Fig. 3 but showing a cabin in place of the lloat tank.

lleseriln-t'l more in detail, the boat resembles the common power boats now in general use, except that the side ribs (3 are bellied outward, as shown more particularly in Figs. 2, I3 and U in order to form a broad bearing on the water. The skeleton, shown more particularly in Fig. 5, comprises an inner shell 7 and an outer shell 2:, connected in spaced-apart relation by trans verse bracing partitions 5). These shells, as is common with devices of this character, are formed of a plurality of curved parallel spaced-apart ribs (3, both sides of which have suitable covers T1 and 81, as shown more particularly in Figs. 3, d and The above construction forms a plurality of separated air chambers 10 disposed about the boat, which, of course, materially assists in its buoyancy. The cock pit 11 has afloor 12 of less width than thewidth of the cock pit, so as to form an opening 13in the bottomof the boat, in order that water which may fiow over the sides thereof, will flow through said opening, as shown by the arrows in Figs. 3 and 6. Further, this cock pit has an opening 14 in the rear of the boat, so that the water will not only flow downward, but will liow rearward out of the cock pit, whereby there is provided an ample outflow of water from the cock pit, especially at the rear end thereof without necessitating an undesirably large or wide opening atany one place. The keel 15 is positioned downward some material distance from the bottom of the sides of the boat, so as to form a keel plate, and is positioned some material distance below the center of the boat, thereby lowering the center of gravity of the same, The keel extends below and to the rear of the under curved stern 1(3 and forms the lower support for the rudder 17.

Dispos d within the space outlined by the under curved stern 16 of'the boat, the keel 15 andg'the rudder 1.7, is the rear propeller lb, whi h propeller is mounted on the lower outer end of an inclined straight shaft- 19 leading to an engine 20, which engine is positioned on the lioor .12, so as to be out of the water 1 much as possible. Positioned below the floor 12 and within the inner shell 7 and above the keel 21 of the inner shell, is a float or air tank 22, suitably braced in position by' means of brackets 23. This tank ailords, in addition to the air chambers 10, means for floating the boat but in place of this tank, av cabin 28 may extend above the 251-, driven from the engine 20 by any suit able connection, upon which shaft and Within the outlines of the boat, are mounted auxiliary propellers 25. v

instead oi utilizing all of the spaces between the inner and the outer shells as air chambers, in certain of the spaces may be positioned lockers 26 or Water tanks 27, as desired. l

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. An open top life boat comprising two shells, one disposed Within the other and spaced. therefrom and means maintaining said shells in spaced relation, said shells and spacing means forming air chambers, the noel; pit of said boat being opened at the bottom and rear thereof, to perinit water noeaeoe being of less Width than the Width of the inner shell to forin openings theretlirough a for the passage of Water falling into said v inner shell, and an air tank disposed beneathsaid floor and Within the outlines of said inner shell and between said openings. In testimony whereof I have slgned my name to this specification in the presence of two subscribing witnesses.
